Definitely focus on form and perspective. Your lines are going off in different directions rather than converging on a single point. Some of the elements in your scene don’t make sense which makes it difficult to understand what you’re trying to show. You seem to have a good intuition for form, it’s just not following any perspective which makes it chaotic. As to how you should practice, I would suggest drawing both. Warm up first with objects in space, paying attention to the horizon line and your vanishing points. The try drawing objects from various angles. But it’s really more about you drawing what interests you but being more mindful of perspective and incorporating what you’ve learned into your work. | Artwod Feedback
